random picture generator

[james7801]

i have this code which works great, only problem is i dont want the same images to be displayed, is there any way to change this to stop the repeated images.

html
<?php include "random.php"; ?></a><?php include "random.php"; ?></a><?php include "random.php"; ?>

php
<?php

srand((float) microtime() * 10000000);

$image[1]['pic']='/images/1.jpg';
$image[1]['link']='x';

$image[2]['pic']='/images/2.jpg';
$image[2]['link']='x';

$image[3]['pic']='/images/3.jpg';
$image[3]['link']='x/';

$image[4]['pic']='/images/4.jpg';
$image[4]['link']='x';

$image[5]['pic']='/images/5.jpg';
$image[5]['link']='x';

$rn = array_rand($image);

echo '<a href="'.$image[$rn]['link'].'">';
echo '<img src="'.$image[$rn]['pic'].'">';

?>

Basically, you want to display n images at random without repetition? If you look closer at [man]array_rand/man, you will see that you can select more than one random entry from the array.

Instead of including random.php multiple times, turn its code into a function, then call that function with an appropriate argument (e.g., 3) to denote the number of random images needed.

EDIT - can be done like laserlight said,

$numberOFresults = 5; // required value
array_rand($image, $numberOFresults);
